摘要：In most WSN applications, the overall traffic profile is very simple as packets only Flow from sensor nodes to the data sinks and vice versa, with very few inter-node exchanges. Despite this simplicity in traffic flows, the WSN is still expected to deliver Sensor data and network control messages with high fidelity in a timely fashion. Aside from packet loss effects presiding over unstable wireless links, the inherent multihop Nature of WSN communications present additional uncertainty in guaranteeing packet transport reliability that the common protocols used in the Internet paradigm are inadequate to handle. In particular, it remains a considerable challenge to preserve the network connectivity in conjunction with low-duty cycles leap-scheduling strategies intended for maximum energy conservation.
